Question

5. Find the area of trapezium whose bases are 150 cm and 30 dm and whose altitude is 9

Answer 1

★=>Given that,

★Length of bases of trapezium = 150 cm and 30 dm

★Length of altitude = 9 dm

We know that, 10 dm = 1 m

★ ∴ Length of bases in m = 1.5 m and 3 m

★Similarly, length of altitude in m = 0.9 m

★ Area of trapezium = 1/2 (Sum of lengths of parallel sides) × altitude

★Area of trapezium = 1/2 (1.5 + 3) × 0.9

★Area of trapezium = 1/2 × 4.5 × 0.9 2.025

★ so,Area of trapezium = 2.025m²
